The Banggai Archipelago () is a group of islands located at the far eastern end of Central Sulawesi, Indonesia. It makes up a regency (kabupaten) of Central Sulawesi Province of Indonesia, created on 4 October 1999 by splitting the existing Banggai Regency into a residual Banggai Regency situated on the mainland of Sulawesi (capital, Luwuk) and a new Banggai Islands Regency (Kabupaten Banggai Kepulauan) then comprising the entire archipelago (with its capital at Banggai town). On 14 December 2012 a splitting of the Banggai Islands archipelago took place with the removal of the more southerly seven districts (including Banggai Island itself, together with smaller islands to its southwest and southeast) from the 13-year-old regency to form a separate Banggai Laut Regency.
The reduced Banggai Islands Regency thus consists solely of the main island of Peleng, the most northern of the Banggai Islands, together with various small offshore islands (of which the largest are Bangkalan and Bakamanpauno Islands off the north coast of Peleng). The regency covers a land area of 2,488.79 km2 and had a population of 109,384 at the 2010 censusBiro Pusat Statistik, Jakarta, 2011. and 120,142 at the 2020 census;Badan Pusat Statistik, Jakarta, 2021. the official population estimate as at mid 2025 was 131,682 (comprising 66,810 males and 64,872 females).Badan Pusat Statistik, Jakarta, 27 February 2026, Kabupaten Banggai Kepulauan Dalam Angka 2026 (Katalog-BPS 1102001.7201) The archipelago is surrounded by the Banda Sea's Gulf of Tolo (Teluk Tolo), and the Molucca Sea. The Peleng Straits (Selat Peleng) separate Peleng from the mainland of Sulawesi.

Endangered Banggai Cardinalfish The Banggai Islands is home to the Banggai cardinalfish. This species has an extremely limited geographic range (5,500 km2) and small total population size (estimated at 2.4 million). The Banggai cardinalfish is composed of isolated populations concentrated around the shallows of 17 large and 10 small islands within the Banggai Archipelago. The species is threatened by extinction due to collections for the aquarium trade.
Climate Salakan has a tropical rainforest climate (Af) with moderate rainfall from August to January and heavy rainfall from February to July.
